For a zero-order reaction, the rate constant is equal to the ____ rate of the reaction.

The rate of a reaction generally ____ with an increase in temperature.

What is the difference between the molecularity and order of a reaction?

Explain why the half-life of a first-order reaction is independent of the initial concentration of the reactant.
